Put a disclaimer like the one I put on this repository: OCA, or the Odoo
Community Association, is a nonprofit organization whose
mission is to support the collaborative development of
Odoo features and promote its widespread use. http://odoo-community.org/

Don't split authors and contributors. Sometimes, the
work made by later contributors is higher than the work
made by the author. I would put only "Contributors".

A better place to host the "template" is
maintainer-tools, not server-tools.

+1 to all your suggestions. And Maxime, thanks for your the
initiative.
